I am creating jobs using Jenkins Organization Folders. I want to continuously build against pull request. However, when I create a pull request, it will be built automatically only the first time. Even if I add commit to pull request, Jenkins does not build automatically. I expect that build will work again when the commit is added to the branch that created the pull request.
I am using the following version of Jenkins / plugin.
GitHub Branch Source Plugin has the following settings.
Also, although I am using Github Enterprise, I think that the configuration of webhook is okay as the build runs instantly when creating the pull request for the first time.
There is two way to resolve this issue
1) You have to configure your github repository so it inform jenkins of a new version: yourRepo/settings/hook&service/service ( the best practice)
or 2) you can configure your jenkins jobs so it check for diff time-to-time if the repo have been update : yourJob/configure/Scan Repository Triggers/Periodically -> 10 min
In my project, we configure both, with a Periodically check of once a day
